EXCLUSIVE: Eurosport's rugby expert Neil Back was pleased to see the smiles return to the England camp, but explains they still have alot of work to do before the crucial game with Tonga.

It gave me a great deal of pleasure to see the smiles back on the faces of the England players and coaches following the win over Samoa.

It was definitely an improved performance from England but I don't think we should get too carried away. With all due respect to Samoa, we should be able to beat them.

I sent Martin Corry a good luck text before the game and it was great to see him go over for two tries. I think he deserved a few things to go his way after the South Africa game.

The early try certainly settled England's nerves and our kicking was better than against South Africa. I think England's all-round game was much improved.

I now expect England to beat Tonga on Friday, which leaves them facing a quarter-final against Australia, which is an altogether different challenge. The Wallabies looked slick against Fiji and were able to up the gears when they needed to.

This Australia side are looking good to me, but we can look at them in more detail once England have secured their quarter-final berth.

Despite England's win, I still have some concerns with the way they are playing. Looking at it from a coaching perspective, it seemed to me that the forwards' work rate off the ball was slow.

I am in no way implying that they lack passion or not trying their hardest, because I know they are, but their indecision can come across as a lack of urgency.

It appears that the forwards do not always know where to run and this is one area where I think England must improve quickly.

The forwards must be told where to go - to get round the corner, to secure the ball, to clean men out, to tackle, to carry the ball. They need clear instructions.

Otherwise they will be slow into the defensive line and players of the calibre of Australian scrum-half George Gregan will take advantage of that.

Rugby is a simple game and because things have not been going well for England I think they must resort to simple plays.

Once the simple things are going well, then by all means move them on a bit. But England must have a pattern they can revert to when the game is not going to plan.

I understand England had a &lsquoclear the air' meeting last week after the South Africa defeat and it seems to have helped.

I gather there were some disagreements among the players and coaching staff as to how they should be playing.

Sometimes senior players have to stand up and be counted and England clearly went back to basics for the Samoa game, which I think was the right decision.

When things go wrong in rugby you should return to &lsquopattern' and England managed this. When it mattered most they denied Samoa the ball and used their kicking to get into the right parts of the field.

On a club level, it was another good week for Leicester. Even though we did not play particularly well, we managed to beat Bath and deny them a bonus point.

That's a good sign and it reminded me of the victories we used to grind out when I was playing. Winning when not playing your best is a good habit to get into.

So far we have won our three warm up games and two Premiership matches. What's more, we done it without most of our senior players, so we'll certainly take that.

But we've got two tough games to come - Wasps away followed by Gloucester at home – and we'll have to up our performance to remain unbeaten before the guys get back from the World Cup.
